"He got depressed right after when his wife died."
with the intended meaning
He got depressed right after his wife died.
If you wouldn't mind, I would very much appreciate your judgment falling into one of the following categories:
(1) It's junk. I'd make a face if I heard someone say it or saw it written and would feel like I definitely wanted to correct it.
(2) It's alright - but I'd rather it was said a different way (e.g. the intended meaning way)
(3) It's perfect. I'd probably say this or write this.
Feel free to qualify your judgment with commentary, of course.
My great linguistic love to you, in advance.
